TMP Piston

In a piston engine, the main bearings are the bearings which hold the crankshaft in place and allow it to rotate within the engine block. Main bearings are usually plain bearings or journal bearings, held in place by the engine block and bearing caps.

Oil pump gears are powered by the crankshaft and in high horsepower or high revving applications the stock oil pump gears can fail due to the increased harmonics, or oscillating of the gear from the added power and revolutions of the crankshaft.

This is a perfect replacement for your stock oem rubber gaskets and seals to replace your worn out or damaged oe rubber seal gaskets to ensure proper seal

The function of a synchronizer is to enable meshing gears to be changed, on a moving vehicle without negative consequences for gears mechanical integrity and interior noise. During synchronization the friction clutch must be disengaged.

A diesel fuel lift pump is a priming pump that transfers fuel from the tank to the fuel injection system. They are called lift pumps, because in most equipment the tank is located below the engine, the fuel has to be lifted up from the tank to the engine.

The water pump pushes coolant from the radiator through the coolant system, into the engine and back around to the radiator. The heat that the coolant picked up from the engine is transferred to the air at the radiator. Without the water pump, the coolant just sits in the system.

Valve stem seals prevent oil from contaminating the air/fuel mixture in the engine’s combustion chamber. They also prevent intake and exhaust gases from contaminating the oil in the cylinder head and the rest of the engine. Valve stem seams are like any other round seal, only much smaller.

A cylinder sleeve (also called cylinder liners or engine sleeves) is a cylindrical metal engine component that protects an engine’s bore and can be used to create bore dimensions after an engine has been over-bored or modified.
